RESUMO
Objective@#This study aimed to examine the demographic characteristics, HIV related knowledge and behavior, correlates of bisexual behavior and status of HIV infection among men who have sex with men only (MSMO) and men who have sex with both men and women (MSMW) in Shandong province.@*Methods@#According to the requirements from "National HIV/AIDS sentinel surveillance program" , a cross-sectional survey was conducted to collect information on demographics, sexual and drug use behaviors, and HIV-related services among MSM in nine sentinel surveillance sites from April to July in 2018. Blood samples were drawn for serological tests on both HIV and syphilis antibodies.@*Results@#A total of 3 474 participants were included in this study. Related information on these participants would include: average age as (31.66±9.01) years; 35.06% (1 218) married or cohabiting with a woman, 50.52% (1 755) had college or higher education, 80.11% (2 783) self-identified as gays and 14.22% (494) self-identified as bisexual men,16.87% (586) ever having sex with woman in the past 6 months, 10.51% (365) ever using drugs. HIV and syphilis prevalence rates were 2.99% (104/3 474) and 2.76%(96/3 474). Through multivariable logistic models, MSMW were more likely to be ≥35 years of age, local residents, self-identified as heterosexual/bisexual/uncertain, ever having commercial sex with man but less likely to consistently use condoms in the past 6 months, less using internet/dating software to find male sex partners and less using drugs. There was no significant differences noticed in the following areas: number of sexual partners in the last week, condom use in the last six months with commercial sex partners, with HIV or syphilis infection and self-reported history of STD in the past year between MSMO and MSMW (P>0.05). HIV-infected MSM were more likely to have the following features, ≥45 years of age, non-local residents, finding male sex partners from the bothhouses, park/toilets or from the internet/dating software, also less likely to consistently use condoms in the past 6 months, using drugs or with syphilis infection.@*Conclusions@#High prevalence of bisexual behavior as well as higher risk of HIV infection were noticed among MSM in Shandong province. It is important to strengthen related surveillance and effective intervention programs for MSM with different characteristics in Shandong province.
RESUMO
A survey was conducted to analyze the HIV testing status and related influencing factors of male sexually transmitted diseases(STD) patients attending 18 county-level hospitals in Shandong Province from July 2015 to August 2016. The HIV detection rate of 1 570 subjects was 77.58% (1 218/1 570), and the HIV-antibody positive rate was 0.99% (12/1 218). Compared with general hospitals patients, urinary and anorectal patients, non-sexual patients, and patients with negative attitudes toward HIV testing, patients were more likely to be tested for HIV from specialized hospitals (OR=3.74, 95%CI:2.53-5.54), the skin and venereal section (OR=1.92, 95%CI: 1.31-2.79), the STD group (OR=2.02, 95%CI: 1.34-3.03) and patients with positive attitude (OR=15.20, 95%CI:10.74-21.52).
RESUMO
Objective To analyze the epidemiological characteristics,dynamic trend of development and related influencing factors of hepatitis C in Shandong,China,2007-2016,also to provide epidemiological evidence for prevention and control of HCV.Methods National surveillance data of hepatitis C from 2007 to 2016 in Shandong was used,with distribution and clustering map of hepatitis C drawn at the county level.Panel Poisson regression was used to explore the influencing factors of hepatitis C at the city level.Results The incidence of hepatitis C in Shandong increased from 1.49/100 000 in 2007 to 4.72/100 000 in 2016,with the high incidence mainly clustered in the urban regions in Jinan,Zibo,Weihai et al.and surrounding vicinities.Majority of the cases were young adults,with 53.16％ (14 711/27 671) of them being farmers.Results from the Multiple panel Poisson regression analysis indicated that factors as:population density (aIRR=1.07,95％ CI:1.05-1.10),number of hospital per hundred thousand people shared (aIRR=1.16,95％CI:1.08-1.24),expenditure of medical fee in rural (aIRR=1.21,95％CI:1.08-1.37) and the proportion of the tertiary industry (aIRR=1.08,95％ CI:1.07-1.09) were all correlated to the incidence of hepatitis C.Conclusions The incidence of hepatitis C had been increasing rapidly in recent years,in Shandong.Prevention and control of HCV should focus on high risk population.In addition,rural,especially in areas with lower economics provision should be under more attentions,so as to find more concealed cases for early treatment.

RESUMO
Objective@#To survey the prevalence of drug resistant HIV-1 in Shandong province in 2013-2015.@*Methods@#WHO truncated sequential sampling technique was adopted by using 77 and 53 samples of newly diagnosed as HIV-1 positive and aged 16-25 years in Shandong province in 2013 and 2015. RNA was prepared and HIV-1 pol region was amplified by RT-PCR and nested PCR. Pol genetic mutation associated with drug resistance was analyzed.@*Results@#The success rates for sequence acquisition of the survey were 100% (77/77) and 94% (50/53) in 2013 and 2015, and the main subtype was CRF01_AE. A total of 2 surveillance drug-resistance mutation(SDRMs) and 3 SDRMs were found by analyzing the 47 sequences each year, sampled in 2013 and 2015, indicating that the prevalence of drug resistant HIV-1 stains was low in 2013, and moderate in 2015. A total of 5 individuals with drug resistant HIV-1 stains found in this study were mainly infected by homosexual transmission (3 cases), and the other two samples were different: one was infected by heterosexual transmission, the other was infected by IDU. The subtype was CRF01_AE (2 cases) , CRF07_BC (2 cases) and B (1 case) . SDRMs for protease inhibitor (PIs), nucleotide HIV-reverse transcriptase inhibitor (NRTIs) and non-NRTI (NNRTIs) were all found in the individuals with drug resistant HIV-1 stains.@*Conclusion@#CRF01_AE were the main HIV-1 subtypes of recently reported HIV-infected individuals in Shandong province, and the HIV-1 drug resistant strains transmission was catalogued as at low and moderate prevalence level in 2013 and 2015.
RESUMO
<p><b>OBJECTIVE</b>To analyze survival time of AIDS death cases receiving Antiretroviral Therapy and related factors.</p><p><b>METHODS</b>A retrospective cohort study was carried out to collect the data on death cases receiving Antiretroviral Therapy by the National HIV/AIDS Comprehensive Response Information Management System. Kaplan-Meier was used to calculate the median survival time, and compare survival time among different groups of age, sex, marriage status, infectious routes, WHO clinical stage, baseline CD4(+)T cell counts, and interval time from the start of ART to HIV confirmation. Life table and survival curve were applied to describe survival distribution. Cox proportional hazard model was used to determine the factors associated with the survival time.</p><p><b>RESULTS</b>Among 142 AIDS death cases, 125 (88.03%) were related with AIDS and 17(11.97%) were not. The total median survival time was 3.100 months (95%CI: 2.279-3.921). The cumulative survival rate was (52 ± 4)%, (33 ± 4)%, (26 ± 4)% in the first 3 months, 3-6 months, and 6-12 months. The median survival time of married or cohabitation group was 2.670 months (95%CI:1.470-3.870), and single (unmarried, divorced, separation, widowed) group was 5.870 months (95%CI: 2.617-9.123). The median survival time of WHO clinical stage I or II group was 5.870 months (95%CI: 3.989-7.751), and WHO clinical stage III or IV group was 1.700 months (95%CI: 0.885-2.515). The median survival time of baseline CD4(+)T cell counts ≤ 50 /µl group was 1.670 months (95%CI: 0.759-2.581), and 51-199 /µl group was 4.400 months (95%CI: 2.735-6.065), and ≥ 200/µl group was 7.100 months (95%CI: 0.000-14.542). The survival time was significantly different among different baseline marital status groups, different WHO clinical stage groups, and different CD4(+)T cell counts groups. The mortality risk of Single (unmarried, divorced, separation, widowed) group was 0.641 times of the risk in married or cohabitation group. The mortality risk of WHO clinical stage III or IV was 1.856 times of the risk in stage I or II. The mortality risk of baseline CD4(+)T cell counts 51-199 /µl group was 0.582 times of the risk in ≤ 50 /µl group, and ≥ 200 /µl group was 0.551 times of the risk in ≤ 50 /µl group.</p><p><b>CONCLUSION</b>The total median survival time was relatively short. Most AIDS deaths happened in the first 3 months or 3-6 months after they received Antiretroviral Therapy, and the mortality trend slowed down in the following months. Married or cohabitation, low-baseline CD4(+)T cell counts, or WHO clinical stage III or IV were found to be the risk factors associated with AIDS death cases receiving Antiretroviral Therapy.</p>

<p><b>OBJECTIVE</b>To investigate the relationship between blood pressure variability, overweight or obesity in patients with essential hypertensive.</p><p><b>METHODS</b>A hundred ninety-one patients with essential hypertension were divided into three groups: normal, overweight and obese according to body mass index (BMI). The characteristics of the variability of 24-hour ambulatory blood pressure monitoring (ABPM) in three groups were compared.</p><p><b>RESULTS</b>Blood pressure overload and variability increased parallel with the increase of BMI. In overweight group, the variabilities of systolic blood pressure at night (nSBPSD) increased 14.10%, the variabilities of diastolic blood pressure at night (nDBPSD) increased 13.15% and the variabilities of mean arterial pressure at night (nMAPSD) increased 15.92% respectively. In the obese group, the above three variabilities increased more significantly (compared to normal group P < 0.05-0.01). However, increases of the three blood pressure variabilities were observed only in the male patients.</p><p><b>CONCLUSIONS</b>The overweight or obesity increased the blood pressure overload and variabilities in patients with essential hypertension. The increases of blood pressure variabilities were observed only in male patients and at night.</p>
